Robust integer and fractional helical modes in the quantum Hall effect

Helical modes are induced in a high-mobility two-dimensional electron gas without strong spin–orbit coupling. This platform provides a versatile playground for investigating compounded quantum Hall edge states.

Synthesizing a ν=2/3 fractional quantum Hall effect edge state from counter-propagating ν=1 and ν=1/3 states

The boundaries of fractional quantum Hall states can host multiple, interacting one-dimensional edge modes, which test our understanding of strongly interacting systems. Here the authors observe the edge-mode equilibration transition that was predicted for the ν=2/3 fractional quantum Hall state.

Coulomb interactions and migrating Dirac cones imaged by local quantum oscillations in twisted graphene

Our understanding of the phase diagram of twisted graphene structures is incomplete. Now, twisted trilayer graphene is examined using a technique that locally images quantum oscillations and shows that a nematic semimetal is favoured at low density.

Proliferation of neutral modes in fractional quantum Hall states

The accepted picture of transport in the fractional quantum Hall effect regime is that neutral modes are present only in hole-conjugate fractional states. Inoue et al.show the presence of upstream neutral modes and energy transport through the bulk in all tested non-hole-conjugate fractional states.

High-efficiency Cooper pair splitting demonstrated by two-particle conductance resonance and positive noise cross-correlation

The Cooper pairs that losslessly conduct current in a superconductor can be split into two spatially separated but quantum mechanically entangled electrons. In this paper, non-local cross-correlation measurements of pairs split within a superconducting wire indicate the efficiency of this process can approach 100%.

Zero-bias peaks and splitting in an Al–InAs nanowire topological superconductor as a signature of Majorana fermions

New data, backed up by simulations, support the existence of Majorana fermions in the one-dimensional topological superconductor that is induced by placing an aluminium superconductor close to an indium-arsenide nanowire.

Crosslinking of Ly6a metabolically reprograms CD8 T cells for cancer immunotherapy

Chronic UV exposure has been associated with immune system suppression. Here the authors show that enhanced tumor growth and resistance to PD1 blockade in mice exposed to UV irradiation is associated with induced expression of Ly6a in CD8 + T cells and that targeting Ly6a enhances anti-tumor immune responses in models resistant to anti-PD1.

Concomitant opening of a bulk-gap with an emerging possible Majorana zero mode

A quantized zero-bias conductance peak (ZBCP) is potentially a signature of Majorana edge mode provided that a topological gap opens in the bulk. Here, Grivnin et al. observe ZBCP at the edge both with and without a superconducting bulk-gap in an InAs nanowire coated with epitaxial Al.

Evidence for 4e charge of Cooper quartets in a biased multi-terminal graphene-based Josephson junction

Here, the authors perform measurements of the interference effects of Cooper Quartets (CQ), observed in a multi-terminal graphene Josephson junction where two terminals are tied by a flux loop. By biasing the superconducting contacts, they identify a superconducting branch attributed to CQ currents, and present evidence for interference between different CQ processes.

Aharonov–Bohm effect in graphene-based Fabry–Pérot quantum Hall interferometers

Interferometers can probe the wave-nature and exchange statistics of indistinguishable particles. Quantum Hall interferometers from graphite-encapsulated graphene heterostructures now enable the observation of the Aharonov–Bohm effect and of robust fractional quantum Hall states.

Strongly coupled edge states in a graphene quantum Hall interferometer

Previous measurements of interferometers based on quantum Hall (QH) edge channels have suggested potential electron pairing effects. Here, the authors investigate the coupling between QH edge channels in graphene Aharonov-Bohm (AB) interferometers, proposing a possible single-particle explanation for the apparent interference phase jumps and AB frequency doubling.
